AMULE SPINNING MACHINE Filed Aug. 14, 1937 Jnrenons Patented Apr. 18, 1939 UNITED STATES PATENT OFFICE MULE-SPINNING MACHINE Application August 14, 1937, Serial No. 159,122 In Germany October 25, 1936 2 Claims.

In mule-spinning machines it was hitherto customary, to drive the carriage by a motor accommodated in a stationary head stock by rope-drive or by a similar means. The means required in this driving manner for the production of the different speeds of the carriage are very complicated as it is generally known.

The invention has for its object to solve the problem to simplify the drive of the carriage. With this object in View a source of power, which can be regulated or controlled, is utilised and made to act upon the carriage by rigid means, such as a rack, piston rod, screw spindles, column of liquid, or the like.

An embodiment of the invention is illustrated, by Way of example, in the accompanying drawing in which the mule-spinning machine with hydraulic arrangement for moving the carriage in and out is shown by Fig. 1 in top plan view, the right hand part being shown only partly.

Fig. 2 shows the part of the hydraulic device which is connected with the carriage.

a is the head stock oi the mule spinning machine, b the supplying mechanism, c the carriage with the spindles d, and e the driving shaft of this carriage. This driving shaft is driven, in known manner, by a motor f mounted on the carriage and through the intermediary of a reversing gear g.

The hydraulic arrangement for the carriage movement consists for instance of an oil pump h and of a motor i for driving the same. These elements are mounted in the head stock of the mule spinning machine. A cylinder lc rigidly connected with the carriage c, is adapted to be shifted to and fro by means of a rod m` of the piston n under the influence of the hydraulic pressure, this rod m being rigidly Xed on the frame a. The piston rod m is hollow (as shown 5 in Fig. 2) and communicates by tubes o with the oil pump h. By a suitable reversing device (not shown) the liquid is alternately conducted into the one and the other cylinder chamber so that the cylinder 7c and with the same also the carriage c moves to and iro. The regulation of this movement can be effected in known manner by regulation of the hydraulic drive (throttling, speed regulation of the drive of the oil pump, and the like).

The improvement is suitable for mule spinners of any kind, for carded-yarn, comb-yarn, cotton, and so forth.

We claim:-

1. A mule-spinning machine, comprising in combination with the carriage, a hydraulic device directly connected With said carriage, a iiuid pump cooperatively connected to said device, and means for regulating the delivery of said pump for regulating and reversing said device for running said carriage in and out.

2. A mule-spinning machine, comprising in combination with the carriage, a hydraulic source of power for running the carriage in and out, a stationary piston rod and a cylinder directly connected with said carriage and reciprocable on said stationary piston rod for transmitting the action of said source of power upon said carriage.
